why do they say I have to do 10,000 steps a day to lose weight
Explain it like I'm 16
10,000 steps is a simple target, not a magic number. Walking uses energy, so doing more of it can help you lose weight, but weight loss mainly happens when you use more calories than you eat over time. You can lose weight with fewer than 10,000 steps, especially if your food intake also changes.
A real-world example
If you usually walk 4,000 steps and increase that to 8,000, you may burn more energy each day. If you do not replace that energy with extra snacks and keep your eating reasonably balanced, this may help you lose weight over time.

Why this matters
A realistic activity target is useful, but your overall eating, movement and consistency matter more than reaching one exact number.
